This paper sets out our framework for measuring the impact of our past interventions using ex post impact evaluations. It incorporates views received from our stakeholders after the publication of the discussion paper in April 2018.
This paper outlines how we use ex post impact evaluation to assess the impact of our past interventions on consumers, firms and markets. It explains:
- why we do ex post impact evaluation
- how we choose specific interventions to study
- how we ensure that our evaluations are robust, impartial, and therefore credible
We assess the effectiveness and impact of our past interventions to develop a strong evidence base to guide our decisions.
You can see our Evaluation Papers on our Evaluating our work page.
We have also separately set out how we measure our impact before we intervene.
We have analysed the responses to our discussion paper and published a feedback statement to accompany the Ex post Impact Evaluation Framework above.
